NOTE TO RESEARCHERS:Please be aware that a formerly "lost" rule for calculating Soundex codes has been rediscovered. This rediscovered rule is called the "Ashcraft" or "H & W" Rule. In addition to the existing Soundex calculation rules, add:

If "H" or "W" separate two consonants with the same soundex number, the "H" or "W" is disregarded, and the second consonant is not coded
